I never said you claimed to make yourself the script author. The problem is, is that you modified the script but are claiming it to be a 1.0 release. On top of that, you are claiming the 1.0 release as being author'd by you in the changelog. The 1.0 release of this script does not have your changes. The initial release did not come from you. The argument regarding "we have no 1.0 release in this project" is invalid, since most this project's scripts don't have an initial release here either, those releases came from eAthena.
In short, you don't just change a version history log because your project doesn't have those releases. Welcome to open source development. Leave my commit history alone, add your own line.
When I pull your clean ups and fixes into Hercules I intend to add a 1.0.1 line to the file with YOUR NAME. Please do me the common courtesy of leaving the initial release comment, author'd by it's original author, me, here in rAthena.
